The Science Behind Permanent Hair Removal
The Tetra Elite is the only device combining 2-in-1 IPL/RF & Diode laser technology with 4 independently FDA-approved wavelengths — engineered to treat every skin tone, every hair type, with clinical precision.
The Science
Why Wavelength Matters
Not all laser hair removal is the same. The wavelength of light determines how deeply it penetrates the skin, which chromophores it targets, and how safely it can be used on different skin tones. Most devices offer one or two wavelengths. The Tetra Elite offers four — giving your provider the precision to match the exact right energy to your unique skin and hair profile.
The Gold Standard for Light Skin
The 755nm Alexandrite wavelength has been the benchmark for laser hair removal on lighter skin tones for decades. Its shorter wavelength is highly absorbed by melanin, making it exceptionally effective on fine, light-colored hair in fair to medium skin. The result: fast clearance, fewer sessions, and outstanding long-term results.
The Universal Workhorse
The 810nm Diode wavelength is the most widely used in professional laser hair removal — and for good reason. It strikes the ideal balance between melanin absorption and skin penetration depth, making it effective across a broad range of skin tones and hair types. Deep follicle targeting means thorough, lasting results with a strong safety profile.
The Breakthrough Wavelength
The 940nm Enhanced Diode is the newest addition to the Tetra Elite platform — and the most significant advancement in laser hair removal in years. Positioned between the standard 810nm Diode and the 1064nm Nd:YAG, it fills a critical gap in the treatment spectrum. It delivers superior efficacy on medium to olive skin tones with enhanced safety margins, reduced thermal risk, and exceptional comfort. This wavelength is what sets the Tetra Elite apart from every other device on the market.
The Solution for Darker Skin Tones
The 1064nm Nd:YAG wavelength is the safest and most effective option for darker skin tones. Its longer wavelength bypasses surface melanin and penetrates deeply to target the hair follicle directly — dramatically reducing the risk of hyperpigmentation or burns that can occur with shorter wavelengths on darker skin. For Fitzpatrick IV–VI, this is the clinical gold standard.
Dual Technology
2-in-1 IPL/RF & Diode Platform
Two technologies. One device. Zero compromises.
The Tetra Elite is not just a multi-wavelength laser — it's a dual-technology platform. By combining Intense Pulsed Light with Radio Frequency (IPL/RF) and Diode laser in a single system, it delivers synergistic energy that targets hair follicles more comprehensively than either technology alone. The RF component adds thermal energy that enhances follicle destruction while the IPL/RF addresses skin texture and tone simultaneously.
IPL/RF Mode
Broad-spectrum light combined with radio frequency energy for enhanced follicle targeting and simultaneous skin rejuvenation.
Diode Laser Mode
Precise, monochromatic laser energy at 755nm, 810nm, 940nm, or 1064nm — selected to match your exact skin and hair profile.
Combined Protocol
Providers can sequence both modalities in a single session for maximum efficacy and comprehensive results.
The Process
How Laser Hair Removal Works
The science of selective photothermolysis
Light Absorption
The laser emits a specific wavelength of light that is selectively absorbed by melanin in the hair follicle — not the surrounding skin.
Thermal Destruction
The absorbed light converts to heat, raising the temperature of the follicle to the point of permanent damage — disabling its ability to regrow hair.
Skin Protection
Advanced cooling technology protects the epidermis throughout treatment, ensuring comfort and preventing thermal injury to surrounding tissue.
Progressive Clearance
Because hair grows in cycles, multiple sessions target follicles in their active growth phase — building toward permanent, lasting reduction.
